[PATCH v2] Minor 'debug_*' function improvements

[Tom Tromey <tromey@adacore.com>]

I wanted to get a summary of a type in gdb and then realized I had
forgotten the function name, so I had to dig around to find it.  This
made me think that perhaps renaming the debug_* functions to all just
be named 'debug' would be an improvement, since it's easier to
remember.

Then I noticed that debug_type and debug_val don't print a trailing
newline.

Finally, I needed to be able to see the contents of a gdb_mpz.

v2 changes these functions to use ATTRIBUTE_USED rather than
ATTRIBUTE_UNUSED, as the former indicates that these should not be
deleted even if apparently unused.
